IMPROVEMENT Ill CHECK-ROWER ATTACHMENTS FOR CORN-PLANTERS.

Specification formingpart of Letters Patent No. 217.401, dated July 1-5, 1879 application filed December 14, 1878.

provement in Check Bower Attachments for Corn Planters; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and

to the letters and figures of reference marked thereon. I

Figure 1 of the drawings is a representation of a top view of my improved attachment for corn-planters, and Fig. 2 is an end view of the same.

1 This invention has relation to improvements in check-rower attachments for corn-planters; and the nature of the invention consists in a transverse shaft journaled in the frame, which shaft is provided at each end with endwiseyielding rods, that are brought alternately by the rotation of said shaft in contact with the ground, and at its middle portion with a cam actuating the seed-slide, the said shaft having also a bevel-gear, engaging a similar gear upon an upright shaft that has at its upper end a pulley, and is actuated by a rope passing around said pulley and reaching across the field, as will be hereinafter more fully set forth.

In the annexed drawings, the letter A designates the frame of a corn-planter, mounted in the usual way upon transporting-wheels, and carrying at each side a seed-box, the valves of which-are alternately opened and closed by a transverse slide. These features are old and well-known, and I make no claim thereto.

B indicates a shaft extending across the frame, and provided at or near the middle of its length with a cam, O. This is engaged by the lever D, fulcrumed on the frame and pivoted at its front end to the seedslide aforesaid. The rotation of shaft B, therefore, causes gear, F, upona vertical shaft, G, having its bearings in a standard, H, upon said frame. This shaft has near its end a sleeve, a, the extremity of which is ratcheted, as shown at b, and carries outside of said sleeve a pulleywheel, H, the hub c of which is correspondingly ratcheted, and isengaged therewith, thus locking the said pulley to the shaft Gr. Rotary motion is imparted to this shaft, and thence through gears E F to shaft B, by means of a rope, J, passing around said pulley and extending across the field. This pulley is removable from its shaft by taking out a key or pin, d, and I may substitute therefor a pulley of greater or less diameter, according to the space between the hills sought to be obtained.

At each end of the shaft B is sccnreda metallic cross-plate, K, having at its extremities the lugs 1, parallel to each other. In these lugs are formed apertures e c, the one above the other, designed to receive the markingrods L. These are usually of iron and extend completely through the lugs Z from side to side, as shown in Fig. 2, and are provided in the space between said lugs with coil-springs 8. These are coiled around the marking-rods and may be secured at one end thereto,though a simple pin, 2', extending through them and preventing the same from escaping from the cross-pieces, will be amply sufficient. The ends of these rods at each rotation of shaft B strike against the ground and form an impression therein, which indicates the position of thehill.

Should the rods at any time strike against a stone or stump or other resisting object, springs s readily yield and allow the said rods to give way endwise, thus preventing them from being bent or broken, and the various parts of the planter attachment from being unduly strained.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the frame A, the shaft B, having cam O, actuating the seedslide, the end arms K, the endwise -yielding rods L, and bevel-gear E, of an upright shaft,

G, having bevel gear F and drivingpulley v In testimony that I claim the above T have H, substantially as specified. hereunto subscribed my namein the presence 2. The combination, with the driving-shaft of two witnesses.
